You then e-mail your translation to Ivanovic. It would be good to try to contact the other translators though, to avoid 2 people working on the same file. Also, somebody might have created a private glossary.

Hi guys, let me just use this thread instead of making a new one: I want to start working on the Arabic translation. I tried to contact the supposed coordinator via e-mail, however my e-mail came back to me with the "unknown recipient" message. Considering that and the fact that only around 1% was translated in total, I guess that the Arabic translation project is dead since long. I want to take care of it. Is it possible somehow? Whom do I contact?

I guess I'll just post this here too. Since there doesn't seem to be any around, I'd like to being the translation for Asturian (asturianu). Should I contact Ivanovic first or just follow the pattern given for the arabic translation?

Great, thanks!
I took a look at your links and I think they will be very helpful, thank you!
Since I am a bit new at all this pardon me if the following question comes off a bit ignorant: How do I edit to the wiki to add my information?
Also, as far as providing the configuration file goes, should I email it to ivanovic like with the .po files?

You might need to register an account with the wiki in order to edit - I don't remember. Login link is on the bottom; I can't find the register link right now. You will also find https://wiki.wesnoth.org/Help:Editing useful.

If you want a wiki account, you have to send a PM to the Wiki Administrators Group, stating your desired account name and email address. Don't forget to put a meaningful subject in the message!
Once your account is created, you'll get a temporary password, which you'll have to change.
